If you see something, say something.
In case you need to report a group for inappropriate content, do as follows.
1. In the group view, click the three little dots on the right side of the join/joined button.
(note: you need to be in the group view to do this, not the party view)
2. Click the "Report this group" button
3. In the pop-up dialog, please try to describe the problem as clearly as possible.
If the problem is the group itself, mention that.
If the problem is caused by an individual user, be sure to mention that too.
